N170
What is the N170?
The N170 wave is an event-related brain potential measured using electroencephalography. The N170 is a negative waveform that peaks at approximately 170 msec after stimulus presentation. It is observed at occipitotemporal sites and with greater amplitude over the right hemisphere. The N170 ERP is observed in response to a variety of facial stimuli, and so it may reflect a neural mechanism for detection of human faces.
What is the evidence for N170 anomalies in people with bipolar disorder?
Low quality evidence in unclear of N170 amplitude and latency changes in people with bipolar disorder compared to controls without any psychiatric disorder.
